Embodiment Construction

[0018] according to Figure 1 to Figure 3 , a variable turbine and / or compressor geometry 1 for a charging device 2 , in particular for an exhaust gas turbocharger in an electric vehicle, comprising a vane bearing ring 3 , guide vanes 5 are rotatably mounted via vane bearing pins 4 In the blade support ring 3. Likewise provided is a control space 6 for an adjusting ring 7 for adjusting the rotational position of the guide vanes 5 , which is arranged on the side of the vane bearing ring 3 facing away from the guide vanes 5 . In addition, the guide vanes 5 have guide vane blades 8 which, on their outer sides facing away from the associated blade bearing pins 4, face a cover disk 9 which is positioned opposite the blade bearing ring 3 and which, for example, can also Designed as guide vane housings. The guide vane vane 8 is in this case arranged in the flow space 14 .

Abstract

The present invention relates to a variable turbine and / or compressor geometry (1) which is used for a supercharging device (2), particularly a waste turbocharger. The variable turbine / compressor geometry is provided with a blade supporting ring and guide vanes (5) which are rotatably mounted therein through a vane supporting pin (4). A control space (6) which is used for an adjusting ring (7) is configured at one side of a vane bearing ring (3), which is deviated from the guide vanes (5). The adjusting ring adjusts rotation position of the guide vanes (5). A guide vane leaf (8) of a corresponding guide vane (5) is positioned to a cover plate (9) which opposes the vane bearing ring (3) at the external surface which is deviated from a related vane supporting pin (4). The variable turbine / compressor geometry is essential in that: the cover plate (9) is provided with through holes (10) which are aligned to the vane supporting pins (4) of the guiding vanes (5). And / or in the vane bearing ring (3) and / or the guide vanes (5), at least one channel (15,15') is arranged in the vane supporting pin (4), for pressure equalization between the control space (6) and a flow space (14) which is provided with the guide vane leafs (8).

Description

technical field [0001] The invention relates to a variable turbine and / or compressor geometry for a charging device, in particular for an exhaust gas turbocharger. Furthermore, the invention relates to a charging device, in particular an exhaust gas turbocharger, which has such a variable turbine / compressor geometry. Background technique [0002] Variable turbine / compressor geometry is used to tune the performance of a supercharging device of an internal combustion engine. In this case the turbine of the supercharging device is driven by the exhaust gas produced by the internal combustion engine, transferring the energy thus obtained to the compressor of the supercharging device. Typically, variable turbine / compressor geometry is used in this case as a means of adjusting boost. Variable turbine / compressor geometry is a mechanism by which the cross-section of the exhaust gas driving the turbine can be varied. This is particularly useful in the case of low quantities of dri...
